''Leuciscus'' is a genus of fish belonging to the family Cyprinidae. They are inland water fishes commonly called Eurasian daces. The genus is widespread from Europe to Siberia. Species broadly distributed in Europe include the common dace ''Leuciscus leuciscus'' and the ide ''L. idus''. The European chubs were formerly also included in ''Leuciscus'', but they are now usually separated in another genus, ''Squalius'' (e.g. the chub, ''Squalius cephalus''). The delimitation of ''Leuciscus'' and ''Squalius'' is not completely resolved; some species have been moved from one genus to the other only in recent years. The genera ''Petroleuciscus'' and ''Telestes'' have also been split off from ''Leuciscus'' recently; for the latter the same holds true as for ''Squalius'' regarding the unclear delimitations. ==Species== There are currently 17 recognized species in this genus: * ''Leuciscus baicalensis'' (Dybowski, 1874) * ''Leuciscus bearnensis'' (Blanchard, 1866) (Bearn beaked dace) * ''Leuciscus bergi'' Kashkarov, 1925 * ''Leuciscus burdigalensis'' Valenciennes, 1844 * ''Leuciscus chuanchicus'' (Kessler, 1876) * ''Leuciscus danilewskii'' (Kessler, 1877) (Danilevskii's dace) * ''Leuciscus dzungaricus'' Paepke & F. Koch, 1998 * ''Leuciscus gaderanus'' Günther, 1899 * ''Leuciscus idus'' (Linnaeus, 1758) (Ide) * ''Leuciscus latus'' (Keyserling, 1861) * ''Leuciscus lehmanni'' J. F. Brandt, 1852 (Zeravshan dace) * ''Leuciscus leuciscus'' (Linnaeus, 1758) (Common dace) * ''Leuciscus lindbergi'' Zanin & Eremejev, 1934 * ''Leuciscus merzbacheri'' (Zugmayer, 1912) * ''Leuciscus oxyrrhis'' (La Blanchère, 1873) (Long-snout dace) * ''Leuciscus schmidti'' (Herzenstein, 1896) * ''Leuciscus waleckii'' (Dybowski, 1869) (Amur ide) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Leuciscus」の詳細全文を読む スポンサード リンク
